I'm struggling to get a good mould from a race seat that i have, and I'm hoping you can give me some advice and help.

This race seat is an infuse carbon part, but it has some metal insert on booth sides, to fix it to the car, making it impossible to make a "direct" mould of it.
I believe that this metal parts are glued with some epoxy glue, so it's literally impossible to remove them.

The metal plates have around 2 ~ 2,5mm thickness and the "bolt" has around 4,5 mm.
As you can see from the pictures below, this metal parts create some undercuts and i'm not sure how can i overcome them.

The "bended" effect of the seat surroundings makes is harder to solve it.


Any help will be appreciated 

Here's some photos so you see what i'm talking about.

This is what I have:



The filler bits are where I've corrected the deformation of the sides.

Looking back at yours; on the back corner there's a radiused point out.  In the non-carbon seats this is a metal load spreader inside the laminate.  The seat needs the threads for the mounting bolts to be in this bit to pass scruitineering.

I didn't understand your last statement.

Are you going to make a mould of your seat?
If so, how are planning to regarding the "bended" edge of the seat?

By the way, with a heat gun the metal plates/fixings came off very easily.
